Özet

Four new configurations realizing current conveyor-based first-order all-pass filters are proposed. Using these configurations two types of first-order voltage-mode allpass filter can be realized. The circuits employ a single positive type second-generation current conveyor (CCII+) and only three passive components. For each topology only a simple component matching constraint is required. To illustrate the design possibilities provided by the introduced circuits an oscillator circuit consisting of the proposed all-pass filters is constructed and experimentally tested.
